Football fans heading into Sixfields stadium on Saturday were encouraged to hand over any smoke grenades and flares, no questions asked.
Northamptonshire Police held a "pyros" amnesty as Northampton hosted Swindon.
Flares and smoke grenades have been let off at Sixfields in the past, which is a criminal offence.
